Built around dual MOSFET push-pull PAs, it is compatible with both handheld and mobile VHF transceivers, making it a versatile choice for 2m amateur radio, commercial VHF, and repeater applications.\u003c\/p\u003e\u003cp\u003eFour selectable power output steps (60W, 100W, 140W, 180W) are controlled from the front panel, alongside mode selection, RX preamp toggle, and SWR metering via an 8-LED multicolour display. A 21dB low-noise receive preamplifier (2.4dB noise figure) and a large thermostatically controlled fan with unique shroud design ensure quiet, reliable operation at full power over extended periods.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFrequency: 138–174 MHz (covers full 2m amateur band)\u003c\/li\u003e\n\u003cli\u003eOutput power: 180W typical from 5W input (4 steps: 60W, 100W, 140W, 180W)\u003c\/li\u003e\n\u003cli\u003eInput range: 1–10W; full output at 5W\u003c\/li\u003e\n\u003cli\u003eDual MOSFET push-pull circuit — stable and efficient\u003c\/li\u003e\n\u003cli\u003eModes: FM, SSB, CW\u003c\/li\u003e\n\u003cli\u003e21dB LNA with 2.4dB noise figure for low-noise receive\u003c\/li\u003e\n\u003cli\u003eRF sense or PTT keying (PTT required for SSB\/CW)\u003c\/li\u003e\n\u003cli\u003e8-LED multicolour display: output power, SWR, error indication\u003c\/li\u003e\n\u003cli\u003eThermostatically controlled fan with shroud — quiet at low power\u003c\/li\u003e\n\u003cli\u003e60dBc harmonic suppression\u003c\/li\u003e\n\u003cli\u003eType N female RF connectors (50Ω, low loss)\u003c\/li\u003e\n\u003cli\u003eRF bypass: max 50W\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFrequency: 138–174 MHz\u003c\/li\u003e\n\u003cli\u003eOutput power: 180W @ 5W input (60\/100\/140\/180W selectable)\u003c\/li\u003e\n\u003cli\u003eInput range: 1–10W\u003c\/li\u003e\n\u003cli\u003eRF bypass: 50W max\u003c\/li\u003e\n\u003cli\u003eHarmonic suppression: 60dBc\u003c\/li\u003e\n\u003cli\u003eRX preamp gain: 21dB (noise figure: 2.4dB)\u003c\/li\u003e\n\u003cli\u003eSupply: 13.8V DC (10.5–14.8V range), 27A continuous \/ 30A peak at 180W\u003c\/li\u003e\n\u003cli\u003eStandby current: 8mA (all off) to 88mA (TX PA + RX LNA enabled)\u003c\/li\u003e\n\u003cli\u003ePTT connector: 3.5mm stereo jack (ground tip)\u003c\/li\u003e\n\u003cli\u003eRF connectors: Type N female\u003c\/li\u003e\n\u003cli\u003eDimensions: 124 × 86 × 197mm\u003c\/li\u003e\n\u003cli\u003eWeight: 1.15 kg\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cem\u003eNote: Requires 13.8V DC @ 30A max.
